MUONFE overview: LEDs aren't correct #2592

Closed Tom-Willemsen closed 7 years ago

Tom-Willemsen commented 7 years ago

On the MuonFE overview OPI some of the LEDs aren't in the correct state. This seems to be because sometimes 0=OFF, 1=ON but other times 0=ON, 1=OFF.

This can probably be fixed by setting a rule on the appropriate LEDs to look for ON/OFF as opposed to 0/1

Let James Lord know when this ticket is complete.

Edit: Some weirdness going on with the Danfysik IOC, dynamically changing On/Off?

After talking with Kathryn the issue is that different models swap the names around as the underlying device comms have swapped around chars for off and on. The above solution will work but we could also do it in the IOC layer, i'm checking if the archive stores the number or the string, if it does we definitely need to swap the IOC.

Archiver appears to store just the enum val, not string. To make that data more clear I'm going to change the IOC.
